Linux References

These are my personal notes from the early days of my Linux learning journey. Over time, I’ve made significant progress, and I decided to share them openly so that others. Whether completely new to Linux or already technical can also benefit.

  • Note: This is not a complete guide. I’m still learning, so this collection will be updated frequently as I gain more knowledge and experience.

I’m a Cybersecurity student at the University of Technology and Applied Science with a strong interest in Purple Teaming the balance of attack and defense. I enjoy hands-on labs, Capture the Flag challenges, and sharing what I learn. This course is part of my journey and is designed to document my journey and build confidence in Linux through simple, practical notes and examples.

References I Used

The following resources helped me build a solid foundation in Linux. You don’t need all of them ; just one is enough to get started and even prepare for Capture the Flag (CTF) challenges or general cybersecurity learning. However, if you’re willing to invest, I highly recommend going deeper with a paid resource, as it covers essential Linux concepts in much more detail.
